DIGITAL CLOCK CIRCUITS

DIGITAL CLOCK CIRCUITS

A Digital Clock can be made easily by using PIC Microcontroller, DS1307 and a 16*2 LCD. I have already posted about Interfacing DS1307 RTC with PIC Microcontroller. The DS1307 RTC can work either in 24-hour mode or 12-hour mode with AM/PM indicator. It automatically adjusts for months fewer than 31 days including leap year compensation

Interfacing of PIC16F84A with DS1307

Interfacing of PIC16F84A with DS1307 (RTC) code and Proteus simulation

This post provides the code for interfacing DS1307 RTC with PIC16F84A microcontroller. This DS1307 RTC has i2c based interface and PIC16F84A doesn’t have any built in i2c modules, so software i2c module is created in the code. This code is written in C language using MPLAB with HI-TECH C compiler. You can download this code from the ‘Downloads‘ section at the bottom

I recently had the urge to create some “eye candy”; Thinking along the lines of my LED Sign (it’s not dead, just waiting on parts!), I chose to create a similar effect, using only a single line of leds, instead of a 5×7 array. Persistence of Vision is some sort of effect, either psychological or

High res cap meter with PIC 16F628

High res cap meter with PIC 16F628

High resolution capacitance meter measures in 0.01pF digits. Total range 0pF to 50uF. – 27th Jun 2011, Updated 25th may 2013. Another PIC based capacitance meter? Although there are a few PIC based “pico” capacitance meters on the internet this design has some advantages over the other designs I have seen; 1. It has very
